For the amount of time I've played recently (20-35 hours a tour, outside of SEA) and one on one training I've receieved (virtually none), I think I'm okay. Maybe get over a 1.x K/D ratio. I'm okay with that since I generally fly the 109F-4 in the LW arenas. It's hard to really rack up kills in the plane since the MG's are pee shooters and very limited cannon rounds. If I fly a 190A-5 I'm pleased with landing 4+ kills. In a F-4, 2+ is a job well done for me. Plus, if the base needs it, I'll fight beyond the cannon rounds. Meaning if I'm out of cannon rounds and I'm with 600 MG pee shooter rounds I'll stick around to dog fight if I think the base fight or defense is worth it. Same thing with fuel, I'll fight till the last drop if need be. If the fight is good, running home to land X amount of kills isn't worth it to me.
I generally avoid flying all furball planes because it's not my style and doesn't please me. I get a lot more satisfaction landing kills in a 30+ ENY plane as opposed to a La7, Niki, P51.....etc. Especially when I shoot down an La7.
